SHAF -BEARING ronnuoxn'r PUMPS.

To all whom it may concern:

seen, a citizen of the United States ofAmerica, and resident'of Cincinnati, county of Hamilton, and State of Ohio, have invented;

certain new and useful Improvementsin Shaft-Bearings for Bucket Pumps, of Which the following islaspecification. Y

An object of my invention is to produce an improved bearing particularly adapted to use in bucket pumps, in which means are provided for preventing the water. lifted by the pump from entering the bearing and washing out the lubricating mater al contained therein. I

A further object is to produce a in which means are provided for preventing the lubricating material from running down the outside of the pump and thereby producing an unsightly appearance.

These and other objects are attained inthe apparatus described in the followingspecification, and illustrated in the accompanying drawings, n which, I I

2 is a transverse sectional view taken on the line 22 of Fig. 1. Fig. 3 .1s a perspective view of a bearing embodying certain details of myinvention and adapted to be used on the crank side of the-pump; Fig. & is a perspective view of ;a bearing embodying certain other details of my invention and adapted to be used on the opposite side of the pump. Fig. 5 is a sectional view taken on the line 5-5 of Fig. 2.

In theillustrat'ed embodiment of my invention, I have shown the usual bucket pump construction comprising a pump casing 6, bucket chain 7, reel 8, for carrying the chain, and mechanism 9, for. operating the reel through the agency of the reel mounting shaft 12. Shaft 12 is mounted in bearings and 11, provided on each side of the pump casing.

Bearing 10, which is adapted to mount the free end 13 of the shaft 12, is provided with an inwardly extending journal boss 14. This boss is of an internal diameter such that the'end 13 may be mounted on rollers 15, a flange 16 being formed on the shaft 12, for the purpose of preventing displacement of the rollers. The outer end of the Specification of Letters Patent.

bearing is closed .by an .integrally formed cap '17, .whi'ch prevents the lubricant containedin the bearing from being discharged to the I exterior thereof I and from] running down the sides of the. pump casing. In

order to prevent the water from the buckets falling upon and washing out theflubri'cant contained in the bearings, I have'provided an inwardly extending semi-circular flange or shield 18, which projects over the flange 16 and directs the water falling on .the

shield, away from the bearing. This flange or shield isso formed, that it extendsbut partially around, the boss 14;, so as to prevent the formation of abasin, which would oatchandretain the water were theshieldto'Ibe extended entirely around the boss.

thereof also being adapted to mount rollers I and being provided with a flange or shield 21, similar tothe shield 18, whereby water from the buckets is prevented from entering the bearing. In addition to this. the bearing is provided with a flange or -Substantially" the same formation is em-n ployed 1n the constructionv of the bearingll,

I the inwardly extending journal boss 19 7 shield 22, extending over the operating mechanism 9 of the pump, so that rain and snow are prevented from aifecting the operation of the pump. Both of the bearing ournal bosses 14 and 19- arepassed through openings contained in the sides of the pump casing and are provided with contacting lugs 23, 2a, 25 and 26, which are provided with openings 27, 28, 29 and 30, adapted to receive r vets or bolts 31 and '32, for the purpose of securing the bearings in place on the pump casing.

y means of the construction above de-c.

scribed, the lubricant contained in the bearings is positively prevented from being washed out, because of the shields 18 and 21 extending into the interior of the casing. and because of the cap 17 and shield 22 outside the casing. The shields 18 and 21 positively prevent the-water from the buckets from being'thrown into such a position, that it will enter the bearings and cause them to corrode, and the cap 17 and shield 22 will prevent any water from rain and snow, to which the pump may be subjected, fromentering the bearings and also detrimentally affecting them. In addition to this, the cap 17 prevents grease contained in the bearing 10 from being washed down theside of the I pump casing and thereby prevents the pump casing from becoming unsightly. Furthermore the shield :22 affords ample protection to the, operating mechanism. -9 andprevents rain-and snow from entering.

Having thus described my invention what I claim is:

1. A bucket {pumpcomprising a casing, a

7 reel carrying shaft located in the casing,

bearings adapted tO"I"fIO11I1t' sai'd reel carrying shaft, mechanism adapted to rotate the shaft, each of said bearings consisting of a boss extending through the leasingand o'i' 'erhanging shields formed on the boss, adapted to prevent entrance of Water to the hearing from the interior 'or exterior of the casing, sald shields extendlng across the top and the crank side of the boss andextending beyendY-thmpoint of connection of the crank" with a shaft.

3. In combination in a-buclret pump a" casing, a bucket carrying shaft located Within the casing, operating mechanism for the shaftya bearing mounted on one side of the casing and adapted'to mount one end. of the s'haft,-said hearing comprising "a journal b0ss,.an overhanging shield formed on the journalb'oss andprojecting within said cas-v ing, and a cap formed integrally with the journal boss and lccate'd on the exterior of "the casing, and "a second bearing adapted to 'me'unt the'opposite end'of theshaft and meiinted on'the 'opposit'eside of the casing,

said second bearing consisting of a journal 'boss "an overhan in shield formed onthe .I 7 t, a u c ournal boss and BXteIldl11g"W1l/l1111 the, casing, and ashield formed onthejournal'boss andfextending tcthe exterior of the casing andi'heyen'd the operating mechanism;
